Procurement Notes

Verify the specific suffix WH6433XTMA1 against official Infineon documentation to confirm tape-and-reel packaging specifications and binning grades. Ensure compatibility with standard SMD reflow soldering profiles defined for the SOT-323 package. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a small-form-factor NPN transistor is required for low-current applications. The 100 mA rating and 45 V breakdown voltage suit standard low-voltage logic levels. Consider the 330 mW power dissipation limit for thermal management in dense PCB assemblies. Verify that the 250 MHz transition frequency meets the signal bandwidth requirements of the target circuit design.

Part Context

This part belongs to the BC847 series of small-signal NPN transistors produced by Infineon Technologies. The series is widely utilized in consumer electronics and industrial control systems due to its reliability and compact footprint. The BC847B variant typically offers specific hFE gain binning compared to other sub-types within the same family, ensuring consistent performance across production batches.

Replacement Considerations

Direct pin-compatible substitutes include the BC847BW from Micro Commercial Components. Other generic equivalents such as the 2N3904 require different packaging and are not direct replacements. Always verify electrical parameters and package dimensions before substituting components in existing designs.
